GEARING.

Specification of Letters Patent. Fermented Sept 314$, 11 Whit).

Application filed January 11, 1908. Serial No. 410,367.

of Madison, Dane county, Wisconsin, have.

invented certain new and useful Improvements in Gearing, of which thefollowing is a specification.

My invention relates to the turret type of lathe and the object of theinvention is to provide a lathe frame of extremely stid and rigidconstruction and very compact in form.

it further object is to provide a lathe having' a standard and housingformed thereon, said housing inclosing the speed controlling mechanismof the lathe chuck and having an opening and a door thereforthroughwhich access may be had to the mechanism inclosed within thehousing.

A further object isto provide a simple compact mechanism whereby a greatvariety of difierent speeds may be obtained for the chuck spindle.

A further object is to provide mechanism whereby the operation of thedifierentspeed devices can be quickly and positively controlled.

My invention consists generally in various constructions andcombinations, all as hereinafter described and particularly, pointed outin the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation of one end of a lathe embodying my invention. Fig.2is an end View of the same. Fig. 3 is a sectional view. -Fig. 4 is a Isectional view on the line y-y of Fig. 3 looking in the direction of thearrow. Fig. 5 is a sectional view on the line w:v' of Fig. 3 looking inthe direction of the arrow. Fig. 6 is a detail of the opposite side ofthe machine from the view shown in Fig. 1, with a portion of the wall ofthe lathe head broken away. Fig. 7 is a detail sectional'view of themechanism for changing the speed of the power feed shaft, taken on line22 of Fig. 2.

In the drawing, 2 represents a base, 3 a standard thereon supporting ahousing or casing 4. within which the principal portion of the speedmechanism is arranged, the

housing and standard being cast in one piece andconstituting the head ofthe lathe. l

have found that by casting these parts in one piece I am able to stiffenthe frame of the lathe very materially, and increase the rigidity ofportions thereof, which in lathes as usually constructed, are subject tomore or less vibration. I am also able to exclude dust and dirt from theoperating mechanism and at the same time render it readily accessiblethrough an opening in the wall of the housing that is closed by aplateor cover 4;. This cover may be readily removed to permit access tothe interior of the housing.

5 is a driving shaft journaled in the end wall of the lathe head, havinga pulley. 5 and carrying two gears 6 and Z of difi'erent sizes. The gear6 meshes. with a gear 8 on a shaft 9 within the lathe head, and a gear10 is mounted on the same shaft outside the said head and through anidle gear 11 drives a gear 12 on a shaft 13 that extends parallel withthe lathe frame. This shaft, which I may term the power mover shaft hasfor its function the moving of the carriage at a rapid, constant speedtoward or from the work. The gear 6 also meshes with a gear 14 that isloosely mounted on a driven shaft 15 above the driving shaft. The gear 7meshes with a gear 16 that is larger than the gear 14 and is alsoloosely mounted on the shaft 15. Both gears 14 and 16 ,may be lockedalternately by means of a key 17 slid- I able in a way 18 in the shaft15. This key is provided with notches 19 that are engaged by a sprin-pressed pin 20 in the shaft 15 and thus t e key is held againstpremature 1 movement.

Either one or the other of the gears 14: and 16 may be locked on theshaft 15 by the adjustment of the key and the movement of one of thegears 6 and 7 transmitted-thereby to the shaft 15. A casing 21 isloosely mounted on the shaft 15 and carries a gear wheel 22that isadapted to engage one of a series of five gears 23, 23,23 ,23 and 23,that are carried by a sleeve 24: that is loosely mounted on achuck'spindle '25. The ear 22 is driven from a pin on 21 that is sphnedon the driven shaft 15 within the casing 21 and operates continuously.The casing 21 is moved back and forth on the shaft 15 by means (if anarm 26 having one end fittin within a fork 2'? on said casing and keyson a sleeve 28 that is loosely mounted on a shaft 29 and has anoperating lever 30. The end of the arm 26- has an anti-friction bearing'within the fork of the casing. When thls casing is moved back and forththe gear 22 to mesh with the iiferent sizes of spindle gears and varythe speed of the spindle.

' The casing 21 besides having a longitudinal movement on the shaft hasa rotary movement to permit the gear 22 to engage the spindle gearsofdifi'erent sizes. For the purpose of oscillating the said casing andthe gear 22' I provide an arm 31 secured on the shaft 29 which isoscillated by a lever 32, said arm 31 havin a link connection 33 with ahanger 34 that is pivoted at one \end on a stud 35. The other end of'thehanger has a series of recesses 36 in its up er edge correspondin to thenumber of gears on the chuck spindle, and ada. ted to receivethe end ofthe casing 21 and a1d in holding the gear 22 against premature movement.connects the casing 21 with a guide rod 38 that is arranged at anincline on the hanger 34. The movement of the casing 21 throughthe-operation of the lever Wlll cause the gear 22 to travel from theplane of one gear on the chuck spindle to the plane of another gearthereon and 'by means of the lever 32 the attendant can oscillate theshaft 29 and rock the arm 3l and raise or lower the casing 21 and thegear 22 according to the size .60 of different sizes on the drivingshaft, it is.

of the gear on the chuck spindle with which the attendant desires thegear 22 to mesh.

A gear 39 is provided on the sleeve 24 and meshes with a gear 40 that iscarried by one end of a sleeve 41 that is mounted on a hub 42 ofa-pinion 43., A hub 44has a pin 45 which passes through a slot 46 in thesleeve 41 and revents rotation of the said sleeve indepen latter to bemoved lengthwise of the shaft 15 independently of the' sleeve tobringthe in"- ion' 43 into mesh with a gear 47 secure on the lathe chuck48 or to separate said pinion and shaft 25 on which asupport or guidefor the lathe tool is mounted. This support forms no part of my presentinvention and is not illustrated herein.

I The hub 44 has a loose connection with the arms of a yoke '49 that issecured on a shaft 50 that is arranged in a substantially up-' rightposition and is provided with an operating crank 51 on its u per end bymeans of which the lathe atten ant can -oscillate the yoke 49 and movethe hub 44 back and forth on the sleeve 41 to connect the pinion 43 withthe chuck ear or disconnect them. The

adjustment of t e gear 22 to mesh with thedifl'erent sized gears on thechuck, spindle will permit the chuck 'to be operated at five differentspeeds and as there aretwo gears evident that fivedifierentspeedsmay beobtained through each one, or ten in, all through the operation of thecrank 51 and theadjustment of the key 17. A clutch52 is splined A link37 1 ently of the hub 42 but allows the gear. Above the chuck spindle isa.

quadrant-shaped a stub shaft 65 an v I tion 66 at its 0 posite end bymeans of which oscillated to move the gear .on the chuck spindle 25between the gear 39 and a ear 53, both of said gearsbeing normally idlebut temporarily locked on the spindle by the engagement .of the clutchtherewith. The clutch 52 has arms 54; connecting it with asleeve 55loosely mounted on the shaft 50 and havin an o erating crank 56, bymeans of whic the c ut'ch52 may be thrown into engagement with eitherthe gear 39 or. the gear 53, as indicated in Fig. 5, and to prevent theoperation of both of them at the same time I provide aloose ball 57 in asocket provided in a plate 58 extending between the hubs of the crank's.The ball 15 adapted to enter recesses 59in the hubs of the cranks 51 and56. In the position shown in Fig. 6 the lower crank willbe locked as theball rests'by gravity in the recess therein. When this crank isoscillated the ball will be raised outof the recess in the hub and willenter the corresponding recess in the hub of the crank 51, beingpartially i in said recess and partially in the socket in the plate,thus preventing this crank from being moved until the crank 56 has beenrei turned to its normalposition. The engagement of the clutch 52 withthe gear 39 will cause the transmission of power from the driving shaftthrough the chuck spindle to the chuck and by means of the differentsized gears on the spindle and the two gears on the driving shaft thechuck may be operated at ten different speeds. The gear 53 meshes withthe gear 59' on'the s'hlftable hub 44 and when the clutch 52 is throwninto engagement with the-gear 53 the power will etransmitted throu thegears 39'and 40 and the gears 59 and chuck, the pinion being withdrawnfrom engagement with the chuck gear by the operation of the oke 49. Bythis means and the 53 to the spindle and gears of .di er'ent size on thechuck spindle and'the driving shaft the lathe chuck may be operated atten other speeds, making a total o 11o thirty difierent speeds at whichthe lathe chuck may be operated bythe. simple compact mechanismdescribed; As heretoforef stated the shaft 13 is utilized when it isdesired to move the carriage rapidly for any pur ose towardv or from thework, and a sha '60 is provided near the shaft 13 through which power issupplied for the normal feed of the carriage. I have illustratedchuckspindle, meshing with an idle gear 62 that is adjustablymounted in aslot 63-of a has an adj usta the plate may plate 64 that is pivoted .on

1e connec 62 toward orfrom the gear 61. By means of this adjustableplate I am able to substitute,

gears of difierent sizes for'the gear 62 and I seams thus vary the speedof the mechanism. A

i the shaft 70 meshing with the idle ear 72 through which a gear73 onthe she 60 is driven. The shafts 65 and 70 are journaled in a plate 74that is removably mounted on the frame of the machine to permit the saidshafts and the plate 64 with the gears carried thereby to be removedfrom the machine.

. This mechanism is designed particularly for screw cuttin and a greatvariety of speeds may be 0 tained through the gears 69 and 68 and thegears on the chuck spindle and driven shaft.

A lead screw 75 is mounted on the outside of the machine frame parallelwith the shafts 13 and 60 and carries an arm 76 which projects through aslot 77 in the lathe head. The inner end of the arm 76 is connected wltha bell crank 78 that is pivoted on the wall of the lathe head andhas onearm in engagement with a collar 79 and is adapted to slide in a way inthe shaft 70 and lock or release the gears 69 on the shaft 70 as thecollar is moved back and forth.
